Посевы лука репчатого занимают более 95% площади, находящейся под всеми видами лука. Из-за высоких вкусовых и питательных качеств лук репчатый – одна из самых распространенных овощных культур в нашей стране – он занимает 64 тыс. га и располагается на третьем месте, уступая капусте и томату. Увеличение объемов производства лука репчатого происходит не только за счет увеличения площадей, занимаемых культурой, но и за счет роста урожайности. Это достигается внедрением в производство новых высокопродуктивных сортов и гибридов, повышением общей культуры земледелия и уровня технологии возделывания. Наряду с созданием гетерозисных гибридов в настоявшее время продолжается и селекция сортов, которые демонстрируют высокие показатели при выращивании в однолетней культуре. Цель исследований: провести испытание образцов репчатого лука разного географического происхождения в однолетней культуре; оценить по основным хозяйственно ценным признакам и выделить в качестве генисточников наиболее адаптивные по основным параметрам. Экологическое испытание 18 образцов репчатого лука отечественной и зарубежной селекции проводили в 2019–2020 годах на опытном участке отдела селекции и семеноводства ВНИИО – филиала ФГБНУ «Федеральный научный центр овощеводства» с постановкой опытов в открытом грунте. В течение вегетационного периода проводили фенологические, биометрические измерения и морфологическое описание образцов согласно методическим указаниям «Изучение и поддержание в живом виде мировой коллекции лука и чеснока». В качестве стандарта использовали сорт Форвард отечественной селекции и зарубежный гибрид F1 Премито. Интенсивность воскового налета на образцах оценивали визуально. Выделены образцы в качестве генисточников хозяйственно ценных признаков: по округлой и округло-плоской форме луковицы выделено 13 образцов, по желто-коричневой окраске сухих покровных чешуй выделено 6 образцов, по содержанию сухого вещества выше 11,0% выделено 7 образцов. Onion crops cover more than 95% of the area under all types of onions. Due to its high taste and nutritional qualities, it is one of the most common vegetable crops in our country-it occupies 64 thousand hectares and is in third place, behind cabbage and tomato. The increase in onion production is not only due to an increase in the area occupied by the crop, but also due to an increase in yield. This is achieved by introducing new highly productive varieties and hybrids into production, increasing the overall culture of agriculture and the level of cultivation technology. Along with the creation of heterotic hybrids, the selection of varieties that show high rates when grown in an annual crop is currently continuing. The purpose of the research: to test samples of onions of different geographical origin in an annual crop; to evaluate the main economically valuable characteristics and to identify the most adaptive sources for the main parameters. Environmental testing of 18 samples of onions of domestic and foreign selection was carried out in 2019–2020 at the experimental site of the Department of selection and seed production of ARRIVG – branch of FSBSI FSVC research center for vegetable growing with the staging of experiments in the open ground. During the growing season, phenological, biometric measurements and morphological description of samples were performed in accordance with the guidelines «Study and maintenance of the world collection of onions and garlic». As a standard, the Forward variety of domestic selection and the foreign F1 hybrid Premito were used. The intensity of wax coating on the samples was assessed visually. Samples were identified as sources of economically valuable traits: 13 samples were identified for the round and round-flat shape of the bulb, 6 samples were identified for the yellow-brown color of dry integumentary scales, and 7 samples were identified for the dry matter content above 11.0%.

Onion dry matter content is very important in terms of processing. The study was undertaken in order to investigate dry matter content inheritance pattern in fresh onion bulb. Five divergent onion genotypes, originating from different geographical areas, have been crossed. Full diallel crossing method (without reciprocals) was applied in order to obtain F1 and F2 generation offspring. Field trial including parents and F1 and F2 hybrids was performed at the Institute for Vegetable Crops experimental plot, Smederevska Palanka. The trial was conducted in randomized blocks, with five replications. Intermediate inheritance pattern prevailed for both F1 and F2 generation. Additive genetic component value was higher than dominant for both F1 and F2 generation, which implies additive effect of genes. Hybrid combination PR x BB was characterized by the highest heterosis value (11.85%). Better general combining abilities were confirmed for three lines in comparison with other lines, whereas special combining abilities were significant for one F1 hybrid. Neither general nor special combining abilities were significant for F2 generation.

Abstract Tomatoes are the main vegetable crops in open and protected ground. Currently, a huge number of varieties and hybrids have been created for industrial and amateur vegetable growing, which differ in the type of bush, yield, early maturity, marketability, disease resistance, color, shape, size, mechanical strength, and biochemical composition of fruits (content of dry substances, sugars, vitamins, mineral salts, organic acids and other vital ingredients). Therefore, not all varieties are equally suitable for processing into functional food products. The article considers the assortment of tomatoes for open ground by yield, marketable qualities and the main indicators of the biochemical composition of the fruit: acidity, dry matter content, sugars, vitamin C, the accumulation of nitrates in the fruit, as well as by taste. As a result of a comprehensive assessment of 9 varieties of tomatoes, the varieties Nepryadva, Belkhavsky and Pulsar were identified, which have high yield, marketability, taste qualities of fruits, vitamin value and suitability for processing into functional products. In breeding for use as sources, the main economically valuable traits are of interest: yield and marketability of fruits – Belkowski, Nepryadva, Pulsar, the size of the fruit – Belkowski, Pulsar; the content of dry substances Belkovsky, Bui-Tur, Nepryadva, Pulsar; vitamin C – Belkowski, Bui-Tur, Pulsar; on the accumulation of nitrate – Nepryadva, Shuttle, Beljavsky, Kulon; taste – Belkowski, Nepryadva, Bui-Tur, Pulsar, Yakhont.

Eggplant is one of the most important vegetable crops known for its nutritive benefits due to the abundance of various bioactive compounds, which include proteins, vitamins, minerals, carbohydrates, phenolics, and dry matter content. In addition, eggplant has significant pharmaceutical properties that have been recently recognized. Eggplant produces secondary metabolites, including glycoalkaloids, antioxidant compounds, and vitamins, which appear to be the major source of its health benefits. It has been reported that there is a considerable correlation between the regular use of phytochemicals and the defense against diseases. Therefore, researchers must analyze the biochemical composition of eggplants to obtain more information about their nutritional quality and health benefits. In this review, an attempt is made to explain the qualitative and quantitative aspects of different biochemicals present in eggplant, in addition to their beneficial health effects.

In 2012–2014, at the Research and Didactic Station of the Department of Horticulture at Wroclaw University of Environmental and Life Sciences (51°19′06′′ N, 17°03′49′′ E), field studies were conducted to evaluate the responses of two sweet maize hybrids to sowing dates (early and optimum) and five methods of maize plant coverings—polyethylene film: perforated (PE), red (PER), green (PEG), polypropylene non-woven fabric (PP), and control (C), with non-irrigation systems. Total yield and morphological characteristics of cobs were compared. In 2012 soluble sugars and carotenoids content were measured. The use of maize cover at the beginning of growth (PE and PER) significantly influenced the number of rows, while PE and PEG increased the number of grains per cob. Covering maize sown at a later date, with polyethylene film and non-woven fabric, ensured better production effects than using such covers after earlier sowing. Signet F1 hybrid was charact0erized by significantly higher sugar content and Rustler F1 by higher lutein and zeaxanthin levels. The application of the optimum sowing date resulted in a significantly higher yield of cobs, by 11.3%, than after early sowing. The yield increase as a result of the applied covers was higher after sowing at a later date. The content of dry matter in grains was positively correlated with the content of sucrose, glucose, and fructose. The change in carotenoids content also depended on the accumulation of dry matter in the kernels. The study confirmed the correlation of sweet maize accumulated growing degree days (AGDD), and revealed dependence of grain quality on dry matter content in the grain.

When growing herbaceous vegetable crops in the world practice, great importance is given to the use of grafting method. The development of environmentally safe methods to increase the yield and resistance of plants to adverse growing conditions is very relevant in vegetable production. One such method in pumpkin crops is grafting. The aim of our work was to study the effect of domestic pumpkin rootstock on growth, development and yield characteristics of cucumber hybrid using grafting method. Grafting on pumpkin species improved the growth and development of plants depending on the rootstock, compared with rootstock plants. The aim of our research was to study the influence of domestic pumpkin rootstock on the growth, development and yield characteristics of the cucumber hybrid (scion). As a scion, the variety (Asylum), recommended for cultivation in protected ground conditions, was used, which was grafted on five domestic rootstocks: 1 (Mozoleevskaya 10), 2 (Karina), 3 (Aphrodite), 4 (Mindalnaya) and Russian selection 5 (Stofuntovaya) pumpkins from vegetable and melon crops. According to the generally accepted method, the graft was grafted (cucumber Asylum) on the rootstocks of pumpkin. Using a sample of pumpkin 1 (Mozoleevskaya 10), flowering began on the fifth day earlier in comparison with non-grafted plants, and when grafting on a sample of pumpkin 4 (Aphrodite), the fruit ripened earlier by six days. To get the greatest increase in early productivity by 30%, it is possible to use both rootstocks. A significant increase in total yield was provided by samples of rootstocks 2 (Karina) – 3.9 kg/m2 and 3 (Stofuntovaya) - 8.0 kg/m2. The grafted cucumber plants with all the rootstocks used were superior to the root ones in height, in terms of the percentage of marketability of fruits and in terms of fruit weight. At the beginning of fruiting on grafted cucumber plants, the number of female flowers increased depending on the sample. In all grafted plants, the dry matter content in the fruit increased significantly. Because of our research, rootstocks 2 (Karina) and 3 (Stofuntovaya) were noted, which are recommended for use in further research breeding work and the production of grafted plants.
